Answer:

37.6

Step-by-step explanation:

DK is half of DS

18.8*2=37.6

Step-by-step explanation:

Since y is directly proportional to x,

we have y = kx, where k is a real constant.

When x = 15, y = 12.

=> (12) = k(15), k = 0.8.

Therefore we have y = 0.8x.

When x = 2, y = 0.8(2) = 1.6.

The answer is y = 1.6 when x = 2.

Answer:

y is directly proportional to x

y=kx, where k is a constant

Now, y=12 when x=15

[tex]12 = k \times 15 \\ k = \frac{12}{15} \\ \boxed{k = 0.8}[/tex]

When x=2,

[tex]y = 0.8 \times 2 \\ \boxed{y = 1.6}[/tex]

Answer:

68.75

Step-by-step explanation:

Measure the length of the parallel sides and add them together. Then multiply this number by the height of the area. Then multiply by ½ or divide by two to find the square footage of the trapezoid.  

13.6 + 5.9= 19.5

19.5 + 8 = 27.5

27.5 x 5 = 137.5

137.5 x 1/2 = 68.75

Wow! What an interesting question, but due to the number limit in math, your answer is 1.70000001e16

Answer:

C. 16 3/4

Step-by-step explanation:

Answer:

Square

x = 2

y = 1

Step-by-step explanation:

Measures of all ll sides of a square are equal.

Therefore,

5x - 4 = 3x

5x - 3x = 4

2x = 4

x = 4/2

x = 2

5y + 1 = 2y + 4

5y - 2y = 4 - 1

3y = 3

y = 3/3

y = 1

Answer:

7 y and 8x first add the 2 number with y together and then you take away the 1 with the x and then you add both of them together

It's volume is 3175 cm.

Answer:

r = 28.28

Step-by-step explanation:

you already gave the equation: sin45°= 20/r

you wanna start by multiplying both sides by r. You do this so that your variable can be in the numerator and it will be easier to solve the equation:

r (sin45°) = 20

Now you divide both sides by sin45°, this will give you your final answer. For this, you have to put it in a calculator:

r = 28.28

P.S, good job on already knowing your equation... when i was learning this it took me a while to get eh hang of it :)

Answer:

y =  -2x + 10

Step-by-step explanation:

The equation in point slope form is expressed using the equation

y - y1 = m(x - x1) where;

m is the slope = -2

(x1, y1) is the point on the line = (4,2)

Substitute into the formula:

y - 2 = -2(x - 4)

y -2 = -2x + 8

y = -2x +8 +2

y = -2x + 10

Hence the required equation of the line is y =  -2x + 10

Answer:

Option D : t = 5s + s/2 is the correct answer.

Step-by-step explanation:

Given that:

t = Combined weight of water and food

s = weight of the snail

Water drank by snail = 5s

Food ate by snail = s/2

Combined weight = Weight of water + Food

t = 5s + s/2

Hence,

Option D : t = 5s + s/2 is the correct answer.

Answer:

Yes, he is correct

Step-by-step explanation:

if you translate each letter ABCDE to A"B"C"D"E" exactly how he stated it turns out right. For example, C just go 8 squares up and then 10 to the right and do the same for the rest.

Answer:

Michael is incorrect;  The shape would have to be flipped at some point, seeing as point B on ADCDE is on the bottom of the shape, whereas point B" on A"B"C"D"E" is on the top of the shape.

Answer Step-by-step explanation:

Let z = 3x +2. Then the equivalent quadratic equation can be written as

 z² +7z -8 = 0

_____

This can be factored as

 (z -1)(z +8) = 0

which has solutions

 z = {1, -8}.

Then the corresponding values of x are found from

 z = 3x +2

 z -2 = 3x

 (z -2)/3 = x

For z = 1,

 (1 -2)/3 = x = -1/3

For z = -8

 (-8 -2)/3 = x = -10/3

Answer:

  D.  (-3, -2)

Step-by-step explanation:

The equations have different coefficients for x and y, so will have one solution. The solutions offered are easily tested in either equation.

Using (x, y) = (-2, -3):

  x = y -1  ⇒  -2 = -3 -1 . . . . False

Using (x, y) = (-3, -2):

  x = y -1  ⇒  -3 = -2 -1 . . . .True

  2x = 3y  ⇒  2(-3) = 3(-2) . . . . True

The solution is (-3, -2).

__

If you'd like to solve the set of equations, substitution for x works nicely.

  2(y -1) = 3y

  2y -2 = 3y . . eliminate parentheses

  -2 = y . . . . . . subtract 2y

  x = -2 -1 = -3

The solution is (x, y) = (-3, -2).

Answer:

Step-by-step explanation:

Answer:

x = 3

y = 5

Step-by-step explanation:

*tip = chose a variable and get by itself one side and then plug it into the other equation

3x + y = 14

y = -3x + 14

2x - 6(-3x + 14) = -24

2x + 18x - 84 = -24

20x = 60

x = 3

3(3) + y = 14

9 + y = 14

y = 5
